BURNER.

Specification of Letters Patent. Patented Nov. 11, 1919.

Application filed May 1, 1917. Serial No. 165,721. 7

To all whom it may'concern:

Be it known that I, CHRISTIAN F. BECK, a citizen of the United States,residing at Steelton, in the county of Dauphin and State ofPennsylvania, have invented a new and useful Burner, of which thefollowing is a specification.

The subject of this invention is a liquid or pulverized fuel burner, andthe objects of the invention are, first, to provide means for atoniizingthe fuel, second, to provide a novel and adjustable atomizing nozzlethird, to provide means for forming a vacuum adjacent the nozzle toconverge the atomized particles, and fourth, to produce a simple andefficient burner.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combi-' nation andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed, without departing from the spirit of theinvention.

A practical embodiment of the invention is shown in the accompanyingdrawings, wherein Figure 1 is a central longitudinal section of a burnerconstructed in accordance with my invention.

Fig. 2 is a detail section on the line 22 of Fig. 1.

Referring to the drawing by numerals 2-- The burner comprises a fuelnozzle 1 which is a pipe with its discharge orifice reamed or beveled,as shown at 2. The discharge end is interiorly threaded to receive thethread pitched teeth formed along the edges of radially extending walls3 which form the stem of an atomizing tip formed with a cone-like head4.The other end of the fuel nozzle 1 is formed with an outwardly extendingannular flange 5 having a hub 6 on the front face thereof. The hub 6surrounds the nozzle 1. A hollow bellshaped member 7 is provided with acentral bore in its flat base or rear end 8 which is threaded to engagethe threads formed on the surface of the hub 6. The curved end of thebell-shaped member 7 is apertured at 9 to permit the end of nozzle 1 topass freely therethrough. A laterally extending hub 10 is formed on themember 7 near the bottom of said member and into this. hub a pipe may bethreaded. The nozzle 1' has an end 11 extendingbeyond the flange 5 whichis threaded for connection to a suitable sup- Ply P P In practice, thedevlce is operated as follows ':A pipe leading from a suitable source ofair or steam supply is threaded into the hub 10. A source of fuel supplyis connected through suitable piping with'the end 11 of nozzle 1. Air orsteam is forced through the bell-shaped member 7 and out at the annularorifice formed by the projection of the nozzle 1 through the aperture 9.This rapidly expelled tubular stream of be formed adjacentjthe exposedcircular 'face of the head 4:, as indicated at 13. Be-

cause of the vacuum at 13, the expelled air or steam will be divertedfrom its regular course and drawn to converge toward the form of a cone.At the same time, the rush of air or steam by the nozzle tip will causea vacuum in the nozzle which will cause fuel to be drawn from the nozzlein a thin tubular stream. This fuel will be violently drawn across theperiphery of the head 4: and thoroughly atomized or broken up. Theatomized fuel will be carried up the inner surface of the convergingportion of the tubular stream and thoroughly mixed with the air or steamat the place of greatest convergence. This mixture may then be lightedat a point immediately beyond the place of greatest convergence.

As will be understood, the tip may be screwed in or out to a point ofmost efficient discharge opening.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

1. In a burner, a casing having a threaded opening formed in the bottomthereof and having an opening in the top thereof, a fuel nozzle having athreaded portion positioned in the threaded opening, and having itsupper end extending through the opening in the top of the casing andterminating at a point above the upper edge thereof, the upper end ofthe fuel nozzle being spaced from the walls of the opening to provide anannular passage way, a tip having channel ways, positioned in thenozzle, said tip havlng a head extending beyond the upper edge of thecasing, and being of a diameter equal to the exterior diameter of thenozzle, to direct a quantity of fuel into the path of travel of airdischarging from the annular passage Way above the casing.

2. In a burner, a casing, a fuel nozzle extending through the casing,said casing having an opening in the upper end thereof, the upper end ofsaid nozzle extending through the opening in spaced relation therewith,and terminating at a point above the casing, a. tip positioned Withinthe upper end of the fuel nozzle, said tip having channel Ways formedtherein, the upper Wall of each channel Way being curved to direct aflow of fuel transversely of the tip and into the path of travel of airdischarging between the casing and Wall of the opening formed in theupper end of the casing.

In testimony that I claim the foregoing as my own, I have hereto ai'hXedmy signature in the presence of two Witnesses.
